My blueline cobalt water will heat great for 2 or three days and then it won't heat for a day or two and the waste tank fills up in 1 job and uses all my freshwater

The water boxes on those machines have a thermo relief valve to keep the water from getting to hot and destroying the pressure pump. When they go bad you will notice two things. One production temps go down and two your waste tank will fill up faster. I would start there. I believe the valve is a cat valve screwed into the water box. One way to tell is after you leave a job, before hooking your water supply line look at the water box and see if it's low or empty. If so change the valve out.

I have ALREADY CHANGED That Out I Was thinking maybe the valve solenoid it has a small line that goes to the waste tank or there is another valve bypass that goes to the pump.the one I replaced was the one that screws into the side at the bottom of the water box 165degree thermal valve

It seems like your bypass solenoid is bad
